BOLTLESS MOLDBOARD AND LANDSIDE PLOW.

Application filed June 5, 1912.

To all whom it may concern:

Be it known that 1, CHARLES XV. MOIVANE, a citizen of the United States,residing at Lynchburg, in the county of Campbell and State of Virginia,have invented a new and useful Boltless Moldboard and Landside Flow, ofwhich the following is a specification.

The invention relates to a boltless moldboard and landside plow.

The object of the present invention is to improve the construction ofplows, and to provide a simple, eiiicient and comparatively inexpensiveplow of great strength and durability, equipped with a moldboard and alandside presenting imperforate or boltless surfaces to the soil, sothat the wear on the moldboard and the landside incident to thefrictional contact of those parts with the soil will not affect thefastening means for securing the moldboard and the landside to a plow.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

Like numerals of reference designate cor responding parts in all thefigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention, 1 designates a plow beam constructedofchanneled metal, or other suitable material and having a downwardlyextending rear portion 2, provided with an integral flattened terminalattaching portion 3, secured by bolts 4 to the lower portion of a fiatinner face 5 of a standard 6. The plow beam is also secured to the upperportion of the standard by a bolt 7 piercing the beam at the web orconnecting portion thereof. The rear portion of the beam is alsoarranged contiguous to a laterally extending lug 8 formed integral withthe upper portion of the standard for the attachment of a moldboard 9,as hereinafter fully explained. By this construction and arrangement,the lower rear end of the plow beam is firmly and securely attached tothe inner face of the standard 6.

The standard 6 is provided at its front with a lower integral foot 10,extending laterally from the inner side or face of the standard andhaving a concave front face 11, which merges into and forms acontinuation of the front face 12 of the upper portion of the standard.The foot of the standard receives a plow point 18 recessed at its rearface to fit the front face of the foot and the standard and to provide ashoulder 14 for engaging the same and secured to the standard by a bolt15 and a lug 16. The bolt 15 has its head countersunk in the plow pointand arranged flush with the front face thereof, and the standard isprovided with an opening 17 for the bolt 15, which is provided at thelower rear face of the foot of the standard with a nut. The lug 16,which is located at the rear edge of the lower laterally extendingportion of the plow point, projects from the lower face of the same andengages beneath the front edge of the foot 10 in a rec'e'ss 18 thereof.The lug and the bolt securely fasten the plow point to the standard inthe usual manner. Thesta'ndard is provided at its outer face with ahori- Zontal longitudinal flange 19 having a beveled undercut lower faceor edge 20 to engage a correspondingly beveled upper edge 21 of alandside 22. The beveled upper edge 21 of the landside is held ininterlocked relation with the undercut flange 19 of the standard by asubstantially vertical bolt 23, arranged at and fitted against the innerface of the lower portion of the standard and extending through aperforatioii 24 of the same adjacent to the flange 19 and also piercingan ear 'or lug 25, eX tending inwardly from a lower ange or enlargement26 of the landside 22. The upper portion of the standard in rear of itsfront edge is extended inwardly and offset from the plane of the lowerportion, and a recess 27 is thereby formed in the outer face of the saidupper portion of the standard, as clearly illustrated in Fig. 7 of thedrawings, and the bolt opening 24 is located in the bottom of the saidrecess 27'. The head of the bolt 23 is preferably arranged at the lowerend thereof and is countersunk in the lug or car 25 while the nut of thebolt is arranged within the recess 27 at the bott'omthe'reof and readyaccess may be had to the same. By this construction, the bolt 23 is notexposed at the outer side face of the landside, which is imperforate.Also this construction enables the landside to be securely fastened tothe standard by a single bolt. The outer face of the lower portion ofthe standard is arranged at a slight inclination and the landside isalso slightly inclined, as clearly shown in Figs. 6 and 7 of the drawins. The front edge of the landside extendsto the front edge of thestandard and fits against the shoulder 14 of the plow point.

The means for attaching the lan'dside to the standard is susceptible toa variety 'of modifications, several of which are illustrated in theaccompanying drawings. In Fig. 13 a relatively short substantiallyvertical-bolt 28 is employed, and to enable this result to beaccomplished the landside 29 is provided at an intermediate pointbetween its upper and lower edges with an inwardly projecting integrallug or ear 30, extending through an opening 31 in the lower portion ofthe standard to the inner face thereof. The head of the bolt 28 iscountersunk in the lower face of the lug or ear 30, and the nut of thebolt is arranged at the upper end thereof similar to that of the'bolt23. The upper edge 32 of the landside 29 is interlocked with an undercutflange 33 of the standard in the man ner heretofore described and thelandside is provided at its lower edge with a flange or enlargement 34,which extends beneath the lower edge of the standard.

In Figs. 14 and 15 of the drawings, the landside 35 is provided at itsbottom with a flange or enlargement 36 having tapered lugs 37,projecting from its upper face and presenting inner inclined facesarranged at an acute angle to the inner face of the landside and formingtapering grooves of recesses to receive the lower edge 88 of thestandard, which is beveled to interlock with the said grooves orrecesses. The upper edge 39 of the landside is beveled upwardly andoutwardly from the inner face and is fitted against a correspondinglybeveled lower edge 40 of a horizontal longitudinal flange '41. Thelandside is also secured to the standard by a short approximatelyvertical bolt 42, arranged similar to the short bolt 28, shown in Fig.13 of the drawings. The bolt 42 pierces an intermediate lug 43 of thelandside, and it eX tends upwardly from the said lug 43 and pierces thestandard at the bottom of the recess 44-.

The moldbo'ard 9, which is imperforate and boltless, is fitted againstthe concave front face of the standard and the foot thereof, and it'scurvature conforms to the configuration of the said faces of thestandaid. The lower and front edges of the moldbo'ard fit againstthecontiguous edges of the plow point, which fori'nsan abutment for andsupports the moldboard, as clearly illustrated in Figs. 1 and 2 of thedrawings, and in order to prevent the moldboard from dropping when theplow point is detached, and also hold the m'oldboard from upward oroutward movement when the plow is in actual operation the moldboard isprovided at its lower edge with an integral projecting l'ug 45,extending downwardly into an opening 'or recess 46 in the foot of thestandard and having a slightly inclined front edge, which engages andinterlocks with a corre's-l'vondingly inclined or undercut front wall orshoulder 47 of the opening 46. This construction enables the plow pointto be readily detached without liability of the moldboard dropping fromits proper position on the standard.

It is obvious that instead of making a complete hole or opening in thefoot, a re cess may be formed of sufficient depth to accommodate the lugand would provide an equivalent construction. In the claims I use theterm socket to cover either a hole or recess, while the term shoulder isdesigned to embrace any form of abut-- ment or stop provided on the footof the standard against which the lug on the moldboard is adapted tobear.

The lug, which constitutes the front attaching means for the moldboard,is also susceptible of a variety of modifications. In Fig. 16 of thedrawings, the foot of the standard is provided at its rear edge with arecess 48 and the front wall or shoulder thereof is engaged by a lug 19,formed integral with the lower or rear face of the moldboard and locatedat a. point in rear of the front edge thereof.

In Figs. 17 and 18 is illustrated an adjustable connection between thefoot of the standard and a lug 50 of the moldboard. The lug 50, which isformed integral with the moldboard, is spaced from the rear edge of thefoot of the standard and is engaged by a plate or member 51 adjustablymount-- ed on the lower face of the foot of the standard. The plate ormember 51 is approximately L-shaped and is provided with a longitudinalslot 52 through which passes a bolt 53, which also pierces the foot ofthe standard. The nut 54 of the bolt engages the plate or member 51 andthe rear port-ion of the latter fits against the lug 51. By means ofthis adjustable connection, any looseness of the moldboard may bereadily taken up and the moldboard may be maintained firmly in itsposition against the standard.

The moldboard, which is fitted at its upper edge against the laterallyprojecting lug or portion 8 of the standard, is held against upwardmovement by a cap plate 55, secured by a bolt 56 in a recess 57 in theupper face oi the said laterally projecting lug or por tion 8. Thelaterally projecting portion 8 is located at the upper edge of thestandard and extends from the inner face of the same, and the moldboardis provided in its upper edge with a notch or recess 58, registeringwith the recess of the lug 8 and receiving the front or outer portion ofthe cap plate 55. The bottom 59 of the notch or recess is downwardly andoutwardly inclined or beveled, and the outer portion 60 of the cap plateis set at a corresponding inclination to engage or interlock with thenotch of the upper edge of the moldboard. The inclined outer portion ofthe cap plate holds the moldboard against upward movement and alsoprevents the same from slipping forwardly or outwardly from beneath it.The bolt 56 pierces the laterally projecting lug or portion 8 andextends through a slot 61 in the cap plate, and it is located in rear ofand is not exposed on the face of the mold board, which is imperforateor boltlese. Also by this construction. the moldboard is secured to thestandard by a single bolt, which is readily accessible.

The top fastening means for the mold board may be modified in variousways, and in Figs. 20 and 21 of the drawings, the standard is providedat the top with a laterally extending lug or projection 62 fittingagainst the rear face of the moldboard, which is provided with anintegral ear or lug 63, provided with a slot 64 receiving a bolt- 65,which also pierces the laterally extending lug or portion 62. The lug orear 63 is engaged by the nut 66 of the bolt 65, and the slot 64:provides for an adjustment of the moldboard.

The moldboard is engaged and secured atits heel by a transverselydisposed spreader bar 67, provided with a downwardly and rearwarcllyextending arm 68, arranged at an inclination and having an outwardlyextending terminal engaging portion 69, which fits in a notch or recessin the rear edge of the moldboard. The terminal engaging portion 69 isset at an acute angle to the arm of the spreader bar, and the coactinginner wall of the notch or recess 70 is beveled to arrange it at anangle to correspond with the said terminal engaging portion to form aninterlocking connection between the heel of the moldboard and thespreader bar. The inner portion of the spreader bar is provided withlongitudinal slots '71, and it is slidably secured by bolts 72 in aguide formed by parallel ribs 78 of a lateral extension 74 of thestandard. The ribs brace and support the spreader bar, and the bolts.which pierce the lateral extension, are pro vided at their rear endswith nuts for engag ing the spreader bar.

' The spreader bar, which firmly braces the heel of the moldboard, maybe connected with the same in various ways, and in Fig. 19 of theaccompanying drawings, the moldboard is provided at its rear face withan integral lug 75, having a beveled rear face to interlock with anangularly disposed terminal engaging portion 7 6 of a spreader bar 77.The rearwardly extending arm 78 of the spreader bar tits against the lug7 5 and corresponds in length to the size of the same. The outer end ofthe spreader bar may be interlocked or secured to the moldboard in anyother suitable manner. The lateral extension 74:, which is set at aninclination, is tapered downwardly and is located at the upper portionof the standard and is provided at its outer edge with an attachingflange 79, extending forwardly from the lateral extension and arrangedat an acute angle to the front face of the same and 1n spaced relationwith the mner face of the standard. The rear upper portion 80 of thestandard is arranged at a slight angle to the intermediate portion ofthe same, as clearly illustrated in Fig. 2 of the drawings and theattaching flange 79 and the angularly disposed rear portion 80 of thestand ard converge and cooperate with the lateral extension to form aculf for the lower ends of plow handles 81. The plow handles 81 aresecured within the cuff to the inner faces of the flange 79 and theangularly disposed portion 80 by bolts 82, or other suitable fasteningmeans. The cuff is open at the front and it obviates the necessity ofsecuring them to the moldboard. The plow handles 81 are connected withthe beam 1 by forwardly converging braces 83, consisting of metallicbars and bolted at their rear ends to the outer faces of the plowhandles and secured at their front ends to the beam 1 in the channels orgrooves thereof.

In Figs. 12 and 12 of the drawings, is illustrated another means forconnecting the plow handles with the standard. The standard 84. isprovided at its rear end with a lateral extension 85, having anattaching flange 86, extending rearwardly from the lateral extension andprovided at its outer edge with an integral lug or car 87 to which thespreader bar 88 is secured. The flange 8G is approximately L-shaped incross section, and it is provided in its lower end with a shoulder 89,forming a stop for a pair of metallic connecting bars 90, which aresecured by bolts 91., or other suitable fastening devices to theattaching flange. The connecting bars, which are arranged at aninclination, have their lower portions fitted together and provided withregistering perforations for the bolts 91, and the upper portions 92 ofthe connecting bars are bent at an angle and diverge upwardly andrearwardly and are provided with perforations to receive bolts forsecuring a pair of plow handles to the said diverging portions of theconnecting bars. The spreader bar 88 has an outer portion of the sameconstruction as the spreader bar 67, and it is adapted to brace andsupport the heel of the moldboard.

It will be observed that there are three connections between thestandard and the moldboard, viz: one between the foot of the standardand the moldboard consisting of a lug $5 on the moldboard whichinterlocks with an opening 46 Or shoulder provided on the standard;another between the standard and the moldboard at the top consisting ofa substantially vertical bolt 56 connecting a lug on the standard with acap piece that engages the upper edge of the nioldboard; and the thirdconnection between the standard andthe heel portion of the moldboardconsisting of a spreader bar having a terminal engaging portion fittingin a notch of said heel portion of the moldboard. While all threeconnections are desirable to make a perfect implement, two only areessential. First, the interlocking connection at the bottom between themoldboard and the standard, which interlocking connection has nopositive fastening means, and, second, a connection between the standardand the moldboard above said interlocking connection, the last-mentionedconnection including a fastening bolt which serves to retain theinterlocking connection in engagement. The exact location of the secondconnection is not material. It may be either at the top or at the heelof the moldboard, but it must be above or at one side of the plane ofthe interlocking connection.

There is a direct coaction between the connection of the spreader barwith the heel of the moldboard and the front interlocking connectionbetween the moldboard and the standard. It will be noted that thespreader bar engages the curved edge of the moldboard at a point abovethe said front connection. The moldboard is thus engaged with thestandard at the bottom and engaged by the spreader bar at the heel.Those two connections serve to prevent the moldboard from slippingforwardly.
